GUNNAR. IVA/2 FRE'DHOLM United States Patent 3,290,792 TRANSPURT-(JONTAINER FOR HYDRO-EXTRAQTORS Gunnar Ivar Fredholm, Forfattarvagen 44, Bromrna, Stockholm, Sweden Filed Feb. 27, 1964, Ser. No. 347,846 Claims priority, application Sweden, Apr. 17, 1963,

- east/63 3 Claims. (Cl. 3458) The invention relates to transport-containers for hydroextractors or washing centrifuges for the transport of laundry-goods from such machines to a machine for drying the goods and has particular reference to transportcontainers adapted to be inserted into the hydro-extractors and having a plate-like bottom portion serving to carry the goods and a centrally arranged tubular boss or sleeve serving as a suspending member for the container.

The present invention has for its object to provide means which will facilitate the unloading of such containers. During the centrifuging process the laundrygoods will be packed along the perforated jacket of the centrifuge basket and form a sleevelike body, which cannot be removed from the container without trouble, when the latter has been lifed out of the centrifuge. This is particularly true, if the container has a large diameter.

In accordance with the invention this drawback is eliminated by dividing the bottom portion of the container into two or more sectorlike portions, which can be tilted outwardly from the suspending member.

In the accompanying drawing are shown two embodiments by way of example of the invention.

FIG. 1 shows a transport-container in vertical section;

FIG. 2 is a plan view of the vessel;

FIG. 3 shows the vessel seen from below;

FIG. 4 is a plan view of a modification of the vessel.

Referring to the drawing the transport-container is provided with a centrally disposed suspending member, comprising a ringshaped body 1 connected to a central conical portion 2, adapted to embrace the driven spindle of the centrifuge basket. At its lower end the conical portion is connected to a rim 3, which may be integral with the portion 2. Said rim is connected by hinges 4 to a disc 5 which is adapted to support the laundry goods during and after the process of centrifuging. The disc 5 is inwardly connected to an annular conical portion 6 normally resting on the rim 3. According to the embodiment illustrated in FIGS. 1 to 3, the disc 5 is constituted by two halfs of a ring, i.e. sector portions with a sector angle of 180". In FIG. 1 the laundry-goods which have been centrifuged are denoted by 7. The goods form in its compressed state a continuous sleevelike body resting on the two discs 5. At right in the FIGURE 1 the laundry-goods and the disc 5 are shown in their normal position when the container has been removed from the centrifuge. This is effected for example, by means of a hook member inserted into the ringshaped body 1 and connected to a telepher device. At left in the FIGURE 1 the disc 5 is shown in a tilted position, in which the disc supports one half of the annular body 7, said half being separated from the other half owing to the tilting movement.

The hinges 4 are placed in such a manner that the discs together with their load will stay on the rim 3 during ice the transport of the container. More particularly, the hinges are disposed at a greater distance from the center of the container than the center of gravity of the disc 5 loaded with the laundry-goods. In FIG. 1 said center of gravity is shown at 8.

The rim 3 and the discs 5 are fashioned to rest upon the bottom portion of the centrifuge basket during the centrifuging process.

It is obvious that the rim 3 need not be made as one continuous ring but can be replaced by arms suited to carry hinges 4.

The container may be provided with a number of sectorlike tiltable discs, for example, three or more, which are each connected to the carrier by a hinge.

FIG. 4 shows an embodiment in which the container is provided with four sectorlike discs 10 connected to the carrier according to FIG. 1, viz. the rim 3, by means of hinges 11. Due to such a subdivision it is possible, by tilting the discs 10 outwardly from the conical portion 2, to break up the annular body 7 of the laundry-goods into four parts instead of two as provided by the construction illustrated in FIGS. 1 to 3.

What I claim is:

1. A container adapted for the transport of laundry comprising a central portion, a rim extending from said central portion, said rim having a free edge at a distance from said central portion, a plurality of discs adapted for resting on said rim and cooperatively defining a ring encircling said central portion, and hinge means connecting said rim at the free edge thereof to each of said discs, said hinge means being at a substantial distance from the central portion to enable outward tilting of the discs with respect to the central portion.

2. A container adapted for the transport of laundry comprising a central portion, support means extending radially from said central portion, a plurality of discs resting on said support means and cooperatively defining a ring encircling said central portion, and hinge means on said support means connecting each disc to said support means, said hinge means for each disc being disposed at a distance from the central portion which is a substantial portion of the radial extent of the associated disc to enable outward tilting of the disc with respect to the central portion.

3. A container adapted for the transport of laundry from a washing machine to a centrifuge, said container comprising a central frusto-conical portion and a peripheral rim extending from said frusto-conical portion, said frusto-conical portion narrowing in a direction away from said rim, said rim having a free edge, at least two hinges at said free edge, and sectorlike discs supported by said hinges and cooperatively defining an enlarged carrying surface for the laundry, concentric with said frusto-conical portion and tiltable outwardly therefrom.
